SELF-ADJUSTING GRAlN-SHOE.

SPECIFICATION forming part of Letters Patent No. 748,741, dated January5, 1904. 7

Application filed December 6, 1902. Serial lilo. 134,124. (N 0 model.)

To all whom it may concern.-

Be it known that I, J on; T.JARDINE, a citizen of the United States,residing at Paso Robles, in the county of San Luis Ohispo and State ofCalifornia, have invented a new and usefulSelf-Adjusting Grain-Shoe, ofwhich the following is a specification.

The invention relates to combined harvesters and grain-separators whichhave tiltable shoes; and the object of the invention is to provideimproved means for maintaining the shoe automatically in a predeterminedposition when the machine is ascending and descending inclines.

A further object of the invention is to provide for quickly andconveniently changing such position of the shoe to vary the inclinationthereof and'for enabling the shoe to be set at any desired inclination.

With the'se'and other objects in view the present invention consists inthe combination and arrangement of parts, as will be hereinafter morefully described, shown in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes inthe form, proportion, size, and minor details may be made within thescope of the claims without departing from the spirit or sacrificing anyof th advantages of the invention.

In the drawings, Figure 'l is-aside eleva-' tion of a portion of acombined harvester I and grain-separator provided withan automatic shoeconstructed in accordance with this invention. v Y view thereof. 'Fig. 3is a detail perspective view of the rack. Fig.4 is a detail perspectiveview of the guide for the counterweight.

Like characters of reference designate corresponding parts in all thefigures of the drawings.

To adequately illustrate the application and operation of the presentinvention, I have shown in theaccompanying drawings a portion of theframe 1 of a combined harvester and grain-separator which is adapted tobe driven through a field and successively cut the heads 'ofthe grain,convey the'same to the threshing apparatus where the grain is separated,thence to carry the grain to the cleaning apparatus, and, finally,discharge the grain into bags. In sucha machine it is Fig. 2 is'avertical sectional to the top of the shoe-frame.

necessary to adjust the shoe when ascending and descending hills inorder that it may be maintained in a predetermined relation with respectto the blower or blast apparatus, and

thereby to' prevent the grainfrom running over at one end of the shoe orbeing blown out of the shoe by the force of the blast, and therefore itis an essential object of the present invention to provide forautomatically maintaining the shoe in a predetermined relation withrespect to the blower, which object is carried out in the followingmanner:

The casing 2 of the shoe is commonly carried by a rotatable rod orrock-bar 3, which is journaled in the main frame of the machine, and inorder that the present automatically-operating device may be connectedthereto one end of the rock-bar is projected beyond one side of the mainframe, as indicated at 4, with its outer end portion journaled in abearing 5, carried bythe upper ends of the braces 6, which inclineupwardly and toward each other and rise from the base or main platformof the machine. A pendulum 7 is intermediately connected to the outerend of the rock-bar and at the outer sides of the braces 6, with itsupper end projected above the top of the shoe. It will of course beunderstood that the connection'between outer'sides of the braces 6in'order that there may be a free and unobstructed path for the thependulum. To, guide the pendulum in its swinging movement, there is ahorizontallydisposed longitudinal-slotted guide-frame 10, which issecured to the braces 6, with the counterweight working in the slotthereof.

The upper end portion of the pendulum, which rises above the top of theshoe,is formed intoa handle 11 and works in the slot of ahorizontally-disposed guide-frame 12, having laterally-projected arms13, which are secured The inner edge of the slot of the frame or bracket1'2 is provided with teeth 14: to form a rack, and the inner side of thehandle 11 is. provided with a tooth or projection 15 to adjnstablyengage :the pendulum and the rock-bar'is loose in orcounterweight 9,carried by the lower end of the rack 14. An upstanding spring-arm 16 hasits lower end secured to the outer side of the pendulum at a point belowthe guide'l i, as indicated at 17, with its upper portion rising throughthe slot of the guide-bracket, inclined outwardly from the pendulum, and

frictionally bearing against the outer smooth so as to be maintained ina relativelyhorizontal position. Should it be desired to have the shoemaintained in an inclined position, the handle is engaged with one ofthe other notches of the rack, according to the inclination desired, andas the counterweight or pendulum always assumes a vertical position theshoe will consequently be maintained in an inclined position.

What is claimed is 1. In a combined harvester and grain-separator, thecombination with a tiltable shoe, of an automatically-operating devicetherefor, said shoe and device having a common pivotal point, and meansfor adj ustably connecting them, whereby the device may maintain theshoe at any predetermined inclination.

2. In a combined harvester and grain-separator, the combination with atiltable shoe, of an automatically-operating device therefor, saiddevice and shoe having a common pivotal point, and means for adjnstablyinterlocking the former to different points of the latter forautomatically maintaining the shoe in any predetermined inclinedposition.

3. In a combined harvester and grain-separator, the combination with atiltable shoe, pivoted at the bottom, of an automaticallyoperatingdevice therefor embodying a pendulum depending below the shoe andfulcrumed independently of the same and in longitudinal alinement withthe axis thereof and also ad justably connected with the shoe.

4. In a combined harvester and grain-separator, the combination with atiltable shoe, of a pendulum fulcrumed independently of the shoe and inlongitudinal alinement with the axis of the same and connected with theshoe above the pivotal point thereof.

5. In a combined harvester and grain separator, the combination with atiltable shoe, of an automatically-operating device therefor embodying apendulum having an adjustable connection with the shoe and fulcrumedindependently thereof and in longitudinal alinement with the axis of thetiltable movement of the shoe.

6. In a combined harvester and grain-separator, the combination with atiltable shoe,

of an automatically-operating device therefor embodying a pendulumfulcrumed intermediately and independently of the shoe, a substantiallyhorizontal rack carried by the shoe and disposed transversely thereof,and a projection carried by the upper end portion of the fulcrum foradjustable engagement with the rack.

8. In a combined harvester and grain-separator, the combination with atiltable shoe, of an automatically-operating device therefor embodyingan intermediately-fulcru med pendulum, a slotted bracket carried by theshoe and receiving the upper end of the pendulum, one side of the slotin the bracket being smooth and the other side being notched to form arack, an upstanding spring-arm carried by the pendulum, one of these twomembers frictionally engaging the smooth edge of the slot, and aprojection carried by the other member and disposed for adjustableengagement with the rack.
